Alan Sugar was known on the British series Dragon's Den as the founder of Amstrad.
Amstrad was founded by Sugar in 1968 and became a major British consumer-electronics company. The name was formed from his initials and surname, standing for Alan Michael Sugar Trading. The company sold products including hi-fi equipment, computers and satellite television hardware.
Sugar joined Dragon's Den as a guest dragon rather than being one of the programme’s original regular investors. His established reputation came from building Amstrad and from his wider business career, while viewers also knew him as the long-serving host of The Apprentice in the UK.
The question is sometimes confused by the fact that Dragon's Den has featured many technology-focused investors. Peter Jones, for example, is strongly associated with technology and telecommunications, but Amstrad’s founder is Alan Sugar.
